Thank you for nice tutorial :)
also suggestion for content about helm charts, helpers.tpl would be also nice topic :)
Hi!
That was an amazing and well done created very very cool video. A really liked it!
Of course I am going to look around your videos and probably will find a solution what I am looking for...but as you mentioned at the end of your video...let ask you...
Question would be: is it possible to manage more than one pod (with one container), for example manage 5 pods with one helm? I mean under the 5 different pods, that all pods have unique containers inside, like one for backEnd, one for UI, one for monitoring, one for DB, etc...
Thanks again your excellent video, and thanks for your answer!
Subscribed 🎉
Thanks
It looks like just a piece of cake now. Thanks anyway. I never thought it would be this easy. 😃
In Helm version >=3.2.0 version, you can create the namespace by passing the `--create-namespace` flag with helm command if not present. Hope this helps someone.
Nice and Sweet. Thank you.
easy cheesy video , such clear explanations
Thanks so much for the video. If working with EKS, do I still need to run the port forwarding command?
Mannnn why I couldn't run into this sooner😩
Wonderful video. I hope you also have tutorial for using helm chart from public repo and overriding it with new values.yaml file
can you create a video on Kubernetes Gatewat API, replacement of k8s ingress controller?
minikube tunnel doesnt seem to work with docker driver on wsl.. ?
Hi, this was a great video to watch for better understanding of Helm. I need to create a helm chart that will deploy MongoDB into kubernetes cluster. Do you know any articles or videos I can follow to help me with this?
Glad it was helpful! Sorry I don't have any recommended articles
8:55 , I got this error
```
Error: UPGRADE FAILED: cannot patch "mydeployment" with kind Deployment: Deployment.apps "mydeployment" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app":"myhelmapp", "tier":"frontend"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable
```
had to delete and create a new helm release
Awesome video... I have a question though. What if you have multiple deployment files with different files for their values (tier=frontend, tier=backend), would one not override the other since the have same key but different values?
Yes they apply in the order you specify them
@@DevOpsJourney Would it be possible to create the backend deployment and its values.yml file and deploy it in a namespace, and then create a frontend configuration with it's own values file and deploy as well?
@@stephenenyidede1125 yes, I'm not 100% clear on exactly what you are deploying, but I can guarantee you the flexibility is there.
im using k3s local setup and it doesn't comes with command minikube tunnel. How to expose external ip? please help me thanks!
Kubectl proxy command is the equivalent of minikube tunnel. You could also look at configuring an ingress resource
What type of shell do you use? Thanks
Windows terminal, with zsh
what is the purpose of showing servicename before the kubectl command if you are not using it?
I have the same question. I guess it’s just getting the service name to do port forward. It’s not printing an output so really don’t understand the purpose.
Great tutorial i need to deploy 25 microservice should i use 1 helm for 1 microservice or each helm for every micro service.
Hey There. You should create separate Helm charts for each microservice and use a single Helm chart called a "Helm Chart Aggregator" to manage the deployments of all 25 microservices. This Helm Chart Aggregator will allow you to deploy, manage, and configure the 25 microservices with a single command.
You also might see some benefit with using Kustomize, especially if you have multiple environments.
Also if you are managing so many microservices, you may want to look into ArgoCD.
Cheers and good luck!
@@DevOpsJourney my app consist of hybrid environment bare metal and azure cloud and it needed to deploy on customer data center i am thinking of using terraform and ansible to make cd on customer data center and azure cloud.
the github doesn't contain up to date info. For example, the readme doesn't show the servicename and kubectl commands.
I tried manually entering them but they don't work . I get "k: command not found"
Edit: I realized it's because you have k as an alias for kubectl
Just FYI. I noticed changing any part of the config map and running "helm upgrade" didn't trigger a redeployment. Only doing "helm uninstall" and only "helm install" will display the new content
thanks for pointing this out.
you can manually restart the pods as well and they will get the new config map values. You can also use something like Kustomize and it takes care of configmap rolling for you.
When you run "helm install" how does helm know where to deploy the stuff? Like in which cluster?
It uses your kubeconfig context, same way as kubectl
Also you can use labels
Sir, what is the use/purpose of helpers.tpl file.
You can store functions and templates in there that your other resources may commonly make use of. It's for more advanced helmcharts - I rarely use it.
I don't know why all UA-camrs made it feel so hard
I have also same dout
the deployment no longer works, pods in crashloop backoff
I'll have a look. Btw are you on a ARM processor like Mac m1 or raspberry pi?
Yup M1 MBP @@DevOpsJourney
Yup M1 MBP, thought purpose of containers was to work on any platform but guess not lol@@DevOpsJourney
I am 🙋♂@@DevOpsJourney
Running on M1 and can't run the image 😕
@@YH-ok8kdI have fixed the issue for m1. I rebuilt the image to support multiple architectures. Let me know if it fixes your issue!
